Sony being sued over Killzone: Shadow Fall's 1080p graphics claims

Sony Computer Entertainment is facing a lawsuit over the marketing of Killzone: Shadow Fall's visuals.

The lawsuit, filed by Douglas Ladore in Northern District California court, claims the game's multiplayer doesn't run at a full 1080p resolution as advertised by Sony through its videos, website, social media and retail packaging.

"Unfortunately, Sony's marketing and on-box representations turned out to be nothing more than fiction," read the lawsuit, according to Polygon.

Following a Digital Foundry report earlier this year that the game's multiplayer runs at a resolution of 960x1080 - and not a full 1920x1080 - developer Guerrilla Games responded that it used a technique named 'temporal reprojection', which the lawsuit claims isn't the "native 1080p that Sony promised".

"In multiplayer mode, however, we use a technique called 'temporal reprojection', which combines pixels and motion vectors from multiple lower-resolution frames to reconstruct a full 1080p image. If native means that every part of the pipeline is 1080p then this technique is not native."

Torkan went on to explain that temporal reprojection isn't like traditional upscaling, which stretches an image in a given direction, but predicts where pixels will be based on previous images to produce a higher resolution.
